What are access modifiers in inner classes?

What are access modifiers in inner classes?

Access modifiers in inner classes determine the visibility of the inner class and its members. They include public, private, and protected.

Can you explain how a private inner class works?

A private inner class can only be accessed by its enclosing class. This encapsulation helps in hiding implementation details.

What about protected inner classes?

A protected inner class can be accessed by its enclosing class and by subclasses, even if they are in different packages.

Are there any restrictions on using public inner classes?

Public inner classes can be accessed from anywhere, but they still have access to the members of the enclosing class, regardless of their access modifiers.
